vovremove: Usage Message
  DESCRIPTION:
      Remove files intelligently, considering
      1- the role of the file in the design flow,
      2- the size of the file,
      3- the time it takes to generate the file.
  
      This operation works only for data in the FILE database.
  
  USAGE:
      vovremove [options]
      
  OPTIONS:
     -everywhere     -- Look everywhere for files to delete.
     -dir <dir>      -- Select a directory under which are the files
                        you want to be deleted.
     -rx  <rx>       -- A regular expression to select files.
     -age <timespec> -- Minimum age of file to be deleted.
     -D   <timespec> -- Maximum cost of recomputation of file.
                        Files that take longer to compute will not be removed.
     -G   <number>   -- Minimum 'Grade' of files to delete: 
                          Grade <== log10( size_of_file / time_to_recompute )
     -doit           -- Really do it, otherwise, just show.
     -help           -- This message.
